Given the points and .

  1. Find the length of the segment determined by the points.

    Use the distance formula if you know it, or sketch the points, make a right triangle, and use the Pythagorean theorem.

    Right triangle with coordinates as follows: (negative 4, comma 2), (negative 2, comma 2), & (negative 2, comma negative 6), with horizontal leg labeled, negative 2 minus negative 4 = 2, vertical leg labeled, negative 6 minus 2 - negative 8.

  2. Write the equation of the line through the points in any form.
